Using external libraries within script (htmlunit-2.56.0)

[NotAnyChef 0]

Hi

I'm trying to use htmlunit within my script to pull data from a webpage

12:54:29: [ERROR] The script had a problem starting:
	java.lang.NoSuchMethodError: 'java.lang.String org.apache.commons.lang3.StringUtils.substringBefore(java.lang.String, java.lang.String)'
	at com.gargoylesoftware.htmlunit.util.UrlUtils.toUrlUnsafe(UrlUtils.java:238)
	at com.gargoylesoftware.htmlunit.WebClient.getPage(WebClient.java:528)
	at OsrsPriceScraper.scrapeData(OsrsPriceScraper.java:32)
	at FlipMain.onStart(FlipMain.java:17)
	at org.dreambot.api.script.AbstractScript.run(AbstractScript.java)
	at java.base/java.lang.Thread.run(Thread.java:833)

However I get this error

 

I've used the library before in a different project, compiled the project to a jar and executed the jar and its worked fine so i'm confused why it's not working

 

I've done some googling and tried adding the .jar's to my lib folder, updated htmlunit to a later version and everything else i could think of

 

Any ideas?

Thankyou

After some more digging it seems both htmlunit and the client use apache.commons.lang3-3 (or some version of it) is there a way to priorities one?

Are you adding the library .jar to the lib file for Dreambot?
